Looks like Marcus Vick has some competition when it comes to sticking up for your ‘pro’ sibling! Greg Jennings’ sister Valyncia went off on Twitter on Sunday as the Packers took on the Vikings and blasted Aaron Rodgers. She even calls Aaron Rodgers overrated. Really?! Of course her tweets were deleted and then her account was closed, but thankfully the good folks at USA Today caught it all and shared with us what she had to say.
